Title: Plumbing question
Post by: mach1mustang351 on November 21, 2010, 06:27:44 pm

I'm doing a TPI swap on my '73 K2500.  I got dual tanks from a donor 75 pickup and I had to run a return line as the '73 didn;t have one.  My question is which port on the sender does what??  Evap, return and Feed.  Thanks for the help.

You should have a 3/8" feed, 5/16" return and 1/4" vent

Thanks.  That makes sense.  I just wanted to verify before I put the bed back on.
